While CPU and battery improvements are always nice, I personally love the added features such as photo syncing. I take a photo on my phone anywhere and it automatically uploads it to my Dropbox in the background so I can view them on my computer when I get home. It's probably one of my favorite features of Dropbox and I hope to see more of this kind of thing in the future. Not to say that other aspects don't need improvement, but I think features like this add a lot of value to the product.
